APPENDIX .. 18 XII. LIST OF DRAWINGS .. 45 OCEAN AUTOMATION TO ALL EQUIPMENT USERS If your gauging device has been equipped with an all Stainless Steel Triple Function Sensor (Material Type 316SS).

4 The triple functions of this sensor are to detect cargo surface level, Ullage, the Interface between two immiscible products such as oil and water, and cargo Temperature. The normal order of the gauging device, response to the products "Ullage level", is a steady horn tone. The normal response to an "Interface level", (" " between a non-conducting and a electrically conducting product such as a petroleum product and water, is a "steady" tone changing to a "beeping" tone, at the interface level. A special note to our chemical customers, is the fact that some chemical cargoes may be inherently conductive.)

5 Therefore, at the surface of a conductive product's Ullage level, a "beeping" tone will be the normal response. As a further note to the above, the change in detection of a non-conductive product Ullage level as a steady tone to that of a conductive product's ullage "beeping" tone, it is not to conclude that the sensor is malfunctioning. The all stainless steel Triple Function sensor is IMO Resolution (XIII) approved, and therefore also meets the International requirements of a petroleum carrier, or a dual classed chemical / petroleum carrier.

6 We hope that this sensor performs satisfactorily for all your applications and we would appreciate any return comments you may have concerning its response to various products.
